LOUIS 1. SMITH, OF ITHACA, NEW YORK.

CARTRIDGE EXTBACTOR FOR BREAKDOWN FIREARMS.

Application filed August 27, 1925.

To all 1071 omit may concern:

Be it known that I, LOUIS P. SMITH, a citizen of the United States ofAmerica, residing at Ithaca, in the county of Tompkins and State of NewYork, have invented certain new and useful Improvements in CartridgeExtractors for Breakdown Firearms, of which the following is aspecification.

This invention relates to improvements in cartridge extractors forbreak-clown firearms.

The primary object of this invention is to provide an extractormechanism for the break-down type of firearm, either of the single ordouble barrel type, wherein a cartridge case will be started or drawn ashort distance from the breech end of its barrel, when the gun isbroken, if the cartridge has not been fired, but will be entirelyextracted or thrown from the breech if it has been fired.

A further object of the invention is to provide a novel retainermechanism for the cartridge case extracting or expelling member whichwill maintain the latter member inoperative when the gun is broken ifthe cartridge has not been fired.

Other objects and advantages of the invention will be apparent duringthe course of the following description.

In the accompanying drawings forming a part of this specification and inwhich like numerals are employed to designate like parts throughout thesame,

Figure 9 shows in end and side elevation a kicker cocking cam,

Figure 10 shows in side and end elevational views a kicker element, and

Figure 11 shows in side elevation and bottom plan a kicker retainerelement.

In the drawings, wherein for the purpose of illustration is shown apreferred embodiment of this invention, the numeral 5 designates theframe portion of a break-down type of firearm which has pivoted to itsfulcrum pin 6 the fore end 7 the fore end and frame being pivotallymoved in respect to each other when the gun is broken.

Suitably carried by the frame 5 is a ham mer 8 having a hammer sear 9associated therewith and employed for retaining the hammer in its cockedposition. This sear 9 is operated for releasing the hammer 8 by thetrigger 10. It is to be understood that the second trigger 11 is alsoprovided with a hammer sear and a hammer of similar construction to theelements designated by the numerals 8 and 9 and that such combinedmechanisms constitute a double barrel type of gun. The hammer 8 ispivoted at 12 and is provided with an ear 13 having connected thereto,by the pivot pin 14, a hammer cocking rod 15 which bears against thecooking cam 16 at its forward end. This cocking cam 16 is pivoted uponthe pin 17 carried by the frame 5.

This cocking cam 16 is illustrated in detail in Fig. 7 and in operativeassembly in Fig. 5 and is shown as including a heel portion 18 againstwhich the hammer cocking rod 15 bears. The cooking cam 16 is furtherprovided with a camming end 19, the function of which will be describedin detail at a later point.

In Fig. 6 there is shown in detail an extractor cam 20 which has anaperture 21 for receiving the fulcrum pin 17 which supthe frame 5 and iscurved at 23 to corre-' spond with the curvature 24 of this forward endof the frame 5 for being arranged to correspond or aline with saidcurvature 24.

' Formed in this curvedface '23 is a notch 25,

the function of which will be described at a later point. A camming end26 projects from the upper portion of the extractor cam 20 and protrudesbeyond the curvature 24 of the forward end of the frame 5 to be receivedwithin the cutout portion 27 of the fore end.

This cutout portion 27 has communicating therewith acylindrically-shaped opening 28 in which is received thecylindricallyshaped stem portion 29 of the kicker cocking cam 30 whichis formed with a camming end 31 against which the camming end 26 of theextractor cam 20 normally bears. This oylindrically-shaped stem portion29 is longitudinally cutaway at 32 for receiving the movement limitingpin 33 which extends transversely of the fore end 7 and functions tolimit the reciprocal movement of this kicker cocking cam 30.

The fore-end 7 in Fig. 3 is illustrated as being formed with theparallel extending slots 34 through which slidably project the stemportions 35 of two kickers 36, one of which is illustrated in detail inFig. 10. These kickers 36 each include an operating arm or plunger 37mounted on the stem 35 and a base block 38 having formed therein alongitudinally extending, internally screwthreaded bore 39 which isintended to receive the threaded end of the kicker rod 40 havingsurrounding the same the spring 41 which bears at its opposite endsagainst the base block 38 and the bearing bracket 42, the said bearingbracket slidably receiving the free end of therod 40.

The fore end 7 is provided with two pairs of depending arms 43, bestillustrated in Fig. 2, which carry the fulcrum pin 44. Pivotally,mounted upon this pin 44, between the said pairs of depending arms 43,is a kicker sear 45, shown in detail in Fig. 8 as including a notchedend 46 and an operating end 47. The notched end 46 of the kicker sear 45is-opera-tively associated with the lower front edge of the base blocks38 of the kickers 36, as best illustrated in Fig. 2.

Pivoted to the fulcrum pin 44 and arranged between the respectivedepending arms of the pairs of arms 43 are the two kicker retainers 48,one of which is shown in detail, in Fig. 11 as including a notched end,49 and a laterally offset upwardly and longitudinally curved operatingend 50.

" The operating ends 50 of the kicker retainers 48 and the operating end47 of the kicker sear 45 project through the end of the fore end 7 shownin elevation in Fig. 4. The kicker retainer operating ends 50 projectthrough the openings 51, shown in Fig. 4 in elevation and in dottedlines in Fig. 2, while the kicker sear operating end 47 projects throughthe opening 52, shown in elevation in Fig. 4 and; in dotted lines inFig. 2. The notched ends 49 of the kicker retainers 48 are associatedwith the independent kicker base blocks 38, as best illustrated in Fig.2.

It is to be understood that the elements shown in Figs. 6, 8 and 9 aresuitable for use with a double barrel gun without being duplicated andthatthe elements shown in Figs. 7, 10 and 11 must be duplicated for adouble bar-rel gun structure. The functioning of the various elementsjust referred to, however, is exactly the same in either a single or adouble barrel structure. Therefore, the functioning of one barrel willbe described, and it is considered that such a description will besufficient for illustrating the operation of either a single or doublebarrel gun.

It will be understood that the hammer 8 is cooked when the fore end 7 ispivoted in res ect to the frame 5 i. e. when the "un is broken. Thispivotal movement of the fore end 7 will cause the cocking cam 16 to bepivoted upon its pin 6 for moving the hammer cocking rod 15longitudinally'toward the hammer 8. thereby pivoting the hammer into itscocked position. The cooking cam 16 will then normally be positionedwith its camming end out of operative relation. with the operating end50 of its kicker retainer. WVhile the hammer 8 is in its cockedposition, the gun may be broken without extracting or discharging fromthe breech end of the barrel the cartridge case located therewith. Thisis accomplished in view of the fact that the kicker retainer 48 isarranged with its notch end 49 in engagement with the lower transverseedge of the kicker base block 38 and with the cooking cam 16 out ofoperative relation in respect to the operating end 50 of the kickerretainer, the latter will not be disturbed and will continue to hold thekicker inoperative when the gun is broken. The kicker sear, however,will be pivoted to disengage its notched end 46 from the base block 38of the kicker every time the gun is broken.

After the hammer '8 has been moved into its fired position, the cookingcam 16 has its cainming end 1.9 projecting into a position to underliethe operating end 50 of the kicker retainer 48. Upon. breaking the gun,with the camming end 19 projecting beyond the end of the gun frame 5,both the kicker retainer 48 and the kicker sear 45 will be will entirelyrelease the kicker 36 and the same will be thrown longitudinally towardthe gun frame 5 by the kicker spring il. This longitudinal movement ofthe kicker 36 will entirely extract the cartridge case from the barrel.Upon returning the gun to its normal or unbroken position, the cam mingend 26 of the extractor cam 20 will be moved into engagement with thecamming surface 31 of the kicker cocking cam 30. This engagement ofthese two elements will cause longitudinal movement of the kickercocking cam 30 which will bear against the base block 38 of the kickerfor moving the same against the tension of the spring 41. This kickerwill be moved by the kicker cocking cam 30 until the notched ends 46 and49 of the kicker sear 45 and kicker retainer 48 will receive the lowertransverse edge of the base block 38 of the kicker, when the kicker willbe held in its cocked position.

It is to be understood that the form of this invention herewith shownand described is to be taken as a preferred example of the same, andthat various changes in the shape, size, and arrangement of parts may beresorted to without departing from the spirit of the invention or thescope of the subjoined claims.
